Patients undergo leukapheresis to obtain leukocytes for generation of autologous dendritic cells (DC). Adenovirus carrying the CCL21 gene is added to the dendritic cells to make the vaccine. Approximately 2 weeks after leukapheresis, patients receive an intratumoral injection of autologous dendritic cell-adenovirus CCL21 vaccine under CT-guidance or by bronchoscopy on days 0 and 7. Patients demonstrating a clinical response are eligible to receive a second round of gene transfer at their discretion and in consultation with the FDA.
